The Calculation of Corrections to the Random Phase Approximation for an Interacting Electron Gas in the Ground State

This work is concerned with the calculation by means of many-particle perturbation theory of the lowest order corrections to the Random Phase Approximation (RPA) description of an interacting electron gas in its ground state. Expressions in terms of the dynamically screened coulomb interaction are obtained for the electron proper self-energy, the electron momentum distribution function, and...

The Nearshore Morphology of Sand Beaches on the Great Lakes Shoreline of Southern Ontario

The nearshore morphology of sand beaches in the Great Lakes usually consists of a ridge and runnel unit in the shallow, inner portion of the nearshore zone and one or more longshore bar and trough units in the deeper, outer portion. These two sets of features are morphologically and genetically different and exhibit spatial and temporal variations indicating the relative importance of envir...

FM Threshold Performance of the Phase-Locked Oscillator

This thesis is principally concerned with the performance of the phase-locked FM demodulator under conditions of interference in comparison to the conventional FM demodulator. The linear no interference performance of the phase-locked oscillator is well known, however this aspect is included in the interests of completeness and reference.

Mechanisms tor threshold effects in the phas...

The Morpho-Ecological Character of Coastal Sand Dunes on the Northern Tombolo, Les Iles-De-La-Madeleine, Quebec

There are marked differences in the morphology and vegetation of the west (Dune du Nord) and east (Dune du Sud) coast dunes of Les Iles-de-la-Madeleine in the southern Gulf of St. Lawrence. The west coast dunes consist mainly of blown-out foredunes succeeded inland by large parabolic dunes. Vegetation is dominated by Ammophila breviligulata with <40% cover, except for the rich flora of cranberr...

The Binding Energy of the Triton Using Repulsive Core Potentials

The binding energy of the tritium nucleus is calculated by the variational method, using static repulsive core potentials.

The Effects of Sb and B Doping on the Conductive Properties of Tin Dioxide (Part B)

This report deals with the effects of various parameters on the resistance and the temperature coefficient of resistance (or the T.C.) of tin dioxide films doped with antimony and boron. The films were produced on cylindrical ceramic substrates by the hydrolysis of SnCl4 and SbCls in the presence of HCl and H3BO3. The T.C. was measured over the range of 25 to 150°C and averaged.

Und...

The Effects of Sb, In, and Sn Doping on the Optical Properties of Tin Dioxide (Part A)

This study was focused on the absorption spectra of tin dioxide thin films on optical quartz substrates. The films were doped with antimony from zero to ten percent, indium from zero to ten percent, and intrinsically, by heating undoped samples in vacuum and air. The surface resistances were also measured.

The results for antimony doping show that the energy required for electron tr...

Linear Polarization Measurements on ²²Na

This thesis comprises linear polarization measurements on gamma rays emitted from the previously observed 1.984, 2.572, 2.969 and 3.059 MeV levels of ²²Na using a Ge(Li) Compton polarimeter. Consistency with previous measurements on parameters characterizing these levels was first checked before assigning J^π = 2⁺ for the 1.984 MeV level and determining that both 2.969 MeV and 3.059 MeV levels ...

﻿Temperature coefficients of reactivity for an 37-element reference design of a thorium oxide fuelled, heavy water moderated and cooled reactor, are calculated. The physical processes which determine magnitude and sign of the coefficients are identified and discussed. Results are given for fresh fuel containing equilibrium concentrations of the fission product Xe-13...

Richard Baxter and the Savoy Conference of 1661

The object of this study is to call into question the well established assumption that Baxter was entirely responsible for the failure of the Savoy Conference and that his combativeness and "overdoing" kept the non-conformists out of the Church.

So vital an aspect in the history of the English Church and the history of non-conformity merits a thorough re-evaluation.

This study deals with applied research in the field of environmentai noise problems, specifically the measuring of noise patterns near Mount Hope Airport originating from subsonic jet aircraft using the present runway facilities. Based on actual measurements the results have been analyzed and reduced to simple contour lines.

An attempt has been made in this study to relate the con...

The Whirlpool Sandstone

A review of the history of the nomenclature of the Medina Formation and of the previous studies of its members, particularly those studies dealing with the source of the Whirlpool sandstone. This is an attempt to show the direction of origin of the detrital materials of the Whirlpool sandstone by a study of the lateral variation of its grain size along the Niagara Escarpment. It is illustrated ...

Effect of Growth Retardants On Phaseolus Vulgaris

A quantitative study is made of the relative sensitivity of Phaseolus vulgaris var. Pinto to several different growth retardants, and to treatment of retarded plants with GA3. The growth of progeny from retarded plants is exam!ned and the cause of the transfer phenomenon is determined to be transfer of the growth retardants themselves to the progeny via the seeds, in some cases through to a...

Description of the ASPLE+ Compiler

The emphasis of my essay are on the description of the language syntax, listing the functions of the major routines, with emphasis put on the use of the current operator - next operator (CO - NO) tables, and a discussion on the code generated by each statement.

A petrographic study has beem made of the contact relations between metagabbro and nepheline gneiss underlain by marble, in Monmouth township, Haliburton County, Ontario.

A bad of hornblende nepheline-garnet gneiss about 80 feetwide trending north-south is underlain at a shear contact by marble. Round inclusion up to 18 inches across of red pyroxene with some spinel and rimmed by ...

Neutron Star Cooling

To determine the detectability of thermal radiation from the surface of a neutron star, the surface temperature as a function of time is needed. To find this, the surface temperature as a function of core temperature is found; this ratio depending on temperature, stellar mass, and magnetic field strength. The energy loss rates from photon emission and neutrino emission are calculated, along...

Part One deals with thin films of SnO₂ which were prepared by ion-beam sputtering, reactive sputtering and anodic oxidation. The films were found to be either amorphous or crystalline in their prepared state.

The structure of the as-deposited amorphous films, as revealed by transmission electron microscopy, presented interesting features: there was a continuous structure in the cas...

This study reports on karren forms on limestone dip slopes, which were recently exposed by deforestation on the Quatsino Formation and observable relationships of the karren features of a specific sl~pe are represented as a detailed map. Also, many relationships of gravitomorphic runnel characteristics are analyzed for significance. Runnel types being considered are Hortonian, decantation a...

A General Study of Reliability In Design

A general study of theory of reliability has been made. The mechanism of failure of mechanical components, the properties of mechanical components, and the interaction of properties responsible for failure have been investigated. Elements of probability and statistics pertinent to reliability theory have been reviewed in brief. The various testing methods for determining component reliabili...

Stability of Open Thin Walled Channel Columns

This thesis deals with the analytical and experimental study of buckling strength, of thin walled channel struts, of different geometrical dimensions. The influence of the dimensions of the columns on the buckling strength has been studied.

The experimental work consisted of testing different channels of thin sheeting to failure. Comparison has been made with the previous work done ...
